Wemos D1 Carrier Board

Three years ago I soldered my first custom-designed PCBs, a set of ESP8266-powered temperature sensors for my apartment!

The original design worked with the ESP8266 modules I had at the time but hasn’t with recent modules (I think I forgot to pull the chip-enable wire high?).

Wemos D1 Mini Carrier Board

This is a spinoff project of my dedicated, single-purpose temperature sensor boards. Instead of trying to be as cheap and small as possible it is intended to be an easy way to connect I2C sensors to the Wemos D1 Mini and probably to esphome.
